Please note there are more species of sand encrusting polyclinids than just Polyclinum aurantium and Synoicum incrustatum. It is therefore advised that sea squirts like this are recorded as 'sand encrusted polyclinid' if their identity cannot be established / verified. This is the advice of Sarah Bowen the author of the Seasearch book, Sea Squirts and Sponges of Britain and Ireland.
